SPECIFICATION forming part of Letters Patent No. 548,100, dated October 15, 1895.

Application filed October 9, 1894. Serial No. 525,423. (No model.) Patented in England .Tuly 19,1894, No. 13.947.

To all whom t may concern:

Be it known that I, WILLIAM TULLY, engineer, a subject of the Queen of Great Britain, residing at London, England, have invented certain new and useful Improvements in Apparatus for Expanding, Beading, andCutting Tubes and for Drilling and Broaching Holes in Tube-Plates and the Like and for Performing Similar Operations, (for which I have obtained a patent in Great Britain, No. 13,947, bearing date July 19, 1894,) of which the following is a specification.

My invention is chiefly designed to provide an improved combination tool or implement which will serve as a tube-expander for securely fastening the ends of tubes in the tubeplates of boilers, condensers, and the like, and which is capable of being readily adapted for performing other operations, viz: the cutting out of old tubes, the reboring or broaching of the holes in the tube-plates, and the holding of the implement in a tube during the beading of the end thereof.

In the accompanying drawings, Figure 1 is a side elevation of my improved implement or apparatus. Fig. 2 is a longitudinal central section showing the mandrel-case and its adj uncts, the roller-case being removed. Fig. 3 is a longitudinal central section of the rollercase. Fig. 4 is a transverse section on the line mfc, Fig. 3. Fig. 5 is a similar view to Fig. 4, the tube-expanding rollers being replaced by the devices for cutting out old or damaged tubes. Fig. 6 is a side elevation of one of the said cutting devices. Fig. 7 is a similar View to Fig. 4., the rollers being replaced by the broaclring-cutters. Fig. 8 is a side elevation of one of the said broachingcutters. Fig. 9 is also a similar view to Fig. 4, the rollers being replaced by the devices for firmly retaining the implement in a tube during the beading of the end of such tube. Fig. 10 is a side elevation, partly in longitudinal section, of one of the said devices. Fig. 11 is a longitudinal central section showing a roller-case and rollers adapted-for tubes of larger diameter. Fig. 12 is a longitudinal central section showing the means for beading the ends of the tubes. Fig. 13 is a sectional elevation illustrating a further modification of my improved apparatus. Fig. la

shows a face view and a transverse section of the detachable cap. Fig. 15 is a transverse section on the line fr m', Fig. 13. Figs. 16, 17, and 18 are side elevations showing, respectively, a roller, a tube-cutter, and a broachingcutter for use with the apparatus shown in Fig. 13.

cavities to engage with the rounded ends of the said rollers or alternative devices, and thus retain the same in the rollercase, while leaving them free to move therein, as required. In other instances I dispense with the said overlapping projections at the ends of the apertures or cavities in the roller-case and arrange them at the sides of such apertures or cavities-that is to say,I make the said apertures or cavities taper from the interior to the exterior of the roller-case, so that while the rollers or alternative devices can move freely in the roller-case, as required, they cannot escape laterally therefrom. In this case I can make the rollers with flat, rounded, or other suitably-shaped ends.

My saidinvention also consists partly in the combination, with the apparatus above mentioned, of breaching and tube-cutting devices and devices for holding the implement in a tube while beading the said tube, which devices are made of such shape that they fit into the apertures or cavities for the rollers in the roller-case and will be retained therein, like the said rollers, by the aforesaid detachable cap.

My said invention further consists in other combinations and improvements hereinafter fully described and claimed.

Referring to Figs. 1 to 11, a. is the mandrelcase. b is the roller-case. c c are the two parts of the mandrel, which are united by a swivel-joint consisting, for example, of 'a pin d, extending through a circumferential groove c2 inthe part c and firmly secured in the part c in such a manner that it can be readily Withdrawn and replaced, for the purpose hereinafter explained. e e are the rollers. f is the screw for adjusting the mandrel, as desired. g is the ratchet for rotating the im- 1c plement.

The rollers e are made with rounded ends, as clearly shown in Figs. 3 and 1l, and to insure the retention of the said rollers in the roller-case b, While permitting their rotation about their axes, the said case is made with apertures b', of the saine width as the rollers le, as -`shovvn in Fig. 4i; butat the inner end of each of the said apertures :an overlapping edge b2 is provided to engage With the `corre"- 2 spending rounded endof the roller e. Tothe cuter end of the case b is secured', byscrewsio'r otherwise, a retaining piece or cap h', formed vvith projections h', Which extend into the apertures bf and engage with the ends of the z 5 rollers e, so that when the said rollers iare in"- serted in the apertures n "and the retaining'- pie'ce h is secured to the roller-'case b the rollers, While fre'eto turn 'abouttheirfaxes and 4te move outward under the action of the mandrel, cannot escape from the roller-case. The said *rollers can, however, when the cap 7L is taken off, be readily removed and replaced by any 'of theaiforesaid devices.

I vmake any 'denen unser of roile'iricasesj 3 5 'b of different diameter and ha'vinglarger 'or s'maller rollers, and I adia'ptllof those Ollel cases fr'use With 'one a'ndthesa'm'e mandreli "case a.

For example, I fmake "each roller-'case l with ia female secrev'v-thread b3, which lits the 4e ferai@ serwrnreaju a y du nl@ dorres'porrdifi'gA @nu of the mandrel-case a, so niet the sata I can nies j 'rollercases rare interchangeable.

only one mandrel-case is required.` -Insmc instances-lalso `make the-mandrel W ith finterchangeable taper or conical parts c', the pin 5o rd being withdrawn when `t`hepart c is tcibe changed.

's'c'rewsj up'on the roller-case 'b in any relquired position, according `to the "ertentj'to v icesta'reall made of t'hesame Width or thickness'as the `rollers e and with Correspondingly-4 shaped ends, so that they can be substituted for the rollers in the roller-case b, as indicated in Figs. 5, 7, and 9, and will be retained therein in the same manner as the said rollers, the cap h being taken off to permit the removal ofthe rollers e and the insertion of either set of the 'alternative devices, and being then again secured in place on the end of the roller-case l).

I make the above-mentioned alternative devices with iiat sides, which bear against the corresponding flat sides of the apertures b', and are thereby efficiently guided and supported. i n i. o Y

The t`ube`-cu`tters 7c are made with sharp seg mental cutting parts 7c', and the broachingcut-ters l are made rwith longitudinal cuttingribs Z. l

Tire devices m are made with a checkered or knnrled surfabem, having a large number of points, which Whjen the said devices are forced outward by the taper part 'c' of the inaudr'e-l will be pressed -`against or into the metal of the tube in su'ch ananner that there will bte no liability to 4turning of the implement in the t'ube 'during the `beadingoperation.

To provide for the use @of the "man'dr'eicase 4and ratchet as 'a ratcliebbrace, I make the man- 'drelca'se d with 'an "external screwJthr'ead "d2, sothat when the screw f `is taken out a suitxable adjustable center ir'nay be lscrewed upon the end of said mandrelhcase, and I provide a drillLsoclret having "a female screw-thread to lfittfh'e inale screw-thread ci on the "other 'end of the said frnalndrel-case AIythus increase `'the number "of 'useful purposes for which the 'apparatus is applicable. If desired, Igform on the roller-casein an external fscrevwthread to receive the said drillrsocket.

instead ot the ratchet shown in the ldrawin'gs, I "sometimes Yuse o'ne having a lever 'or "handle formed with a bok to "cover 4or inclose 'the rat'chetsvvheel, a bolt-"patri b'eingip ro'vided, whichis held in engagement with the teeth of the said Wheel byla spiralior'otherisuitable spring.

When my improvediapparatus is to be used 1for beading the tubes, ith'e usual sleeve or cole lar n, provided with beading-rollers n', is fitted -upou the 'rollercase lb, as shown in Fig. 12, fand is arranged to "be adjusted as Vthe "beading `operation progresses `by Ameans "of "a nut j?, screwed upon the roller-(case band lp`ro' vided'With'tdmmy-holes'r other means Whereby it may b'e `readily turned.

`In 'the arrange'mentshovvn in Figs. 13 to -18 the cavities b lof the r'ollercase b are made slightly'taiperin from the interior to the exte-V riorrasshovvn-in f ig. ,15,ffo`r thepurposefoflpre# venting theescape of 'the rollers orother devices laterally therefrom, thetaper of the 'said cavities bein'gsuch that when the rollers have been moved outward to the predetermined limit their fnrther'out'ward movement will be `prevented 'by thelconvergingsidesof the said cavitieafa'nd the cap "7L `is madepas shown in IOO Fig. 14, Without any projections. The rollers e in this modification are made with iiat ends, the cutters lo Z andthe devices for holding the implement in the tube being made of corresponding shape.

I am aware of the United States patent to John Lohges, No. 270,446, dated January 9, 1883, and I make no claim to the apparatus described in the specification of the said patent.

What I claim is- 1. A combination tool for expanding boiler and other tubes, cutting out old tubes and breaching holes in tube-plates, which tool consists essentially of the interchangeable expanding, cutting and holding devices of the same general dimensions, theroller-case having radial apertures open at the extremity of said case to admit either set of said expanding, cutting and holding devices, and the removable cap on the extremity of said case to retain said devices in the apertures, said apertures being made with overlapping 0r converging sides to prevent the escape of said devices laterally from said case, as hereinbefore described.

2. In a combination tool for the purposes above specified, a roller-case or holder having lateral or radial apertures for the rollers open at one end of said case or holder, and a removable cap secured on the extremity of said case or holder to retain said rollers in the apertures, the Walls of said apertures converging toward the exterior of saidcase or holder to prevent the escape of said rollers laterally therefrom, substantially as described.

3. In a combination tool for the purposes above specified, a roller-case or holder having a screw-thread at one end and adapted to be secured on a corresponding screw-thread on the end of a mandrel-case, and having lateral or radial apertures for the rollers open at the other end of said case or holder, and a removable cap secured on the extremity of said case or holder to retain said rollers in the apertures, the walls of said apertures converging toward the exterior of said case or holder to prevent the escape of said rollers laterally therefrom, substantially as described.
